What does this have to do with placing batteries on the ground to watch them discharge, oh sorry we hijacked your thread.

Exactly why I bowed out of that particular soon-to-be-argument, but some insist on making it a federal case...

What I can vouch for is the fact that when I worked at AutoZone, we had a special on DuraLast top-post batteries of a certain size group. They were stacked on the concrete floor as a display. EVERY SINGLE ONE of the batteries on the bottom row (that sat on the CONCRETE) had problems. None of the others did. Can anyone EXPLAIN that? Call it what you want. Agree to disagree. Back to the OP's build... What's new?

Likewise here...a buddy owned a half dozen motorcycle shops and learned the same "phenomena" the hard way. For whatever reason, batteries discharge when they sit on concrete floors. Seems counter-intuitive since the cases should act as insulation but it happens all the same. Any rocket scientists out there know why?

For what it's worth, Snopes has never shown credentials of any sort, shown that any real research is done, who (if anyone) actually checks the facts, nor do they provide proof of why the subject matter is "proven" or "debunked". C'mon, folks, even Mythbusters at least runs a real test and shows scientific evidence to back up their findings. Anyway, I don't think the OP is getting a charge out of this, nor do I think it turns them on... "Type faster, I hear off-subject arguments..."
